    You must buy this book. I recommended it on here four or five years ago and enough people bought it that the price of used copies went to over 200 dollars. Now it appears to be available again, Maybe...

    Whenever I am not working on my waxes I keep them in a tub of water. That way they stay exactly in the shape I made them in, and away from damage by other things as well.

    I use a factor of 10 when I am pouring my sculptures, and I add a bit more for safety. I want the pouring cup to be full. Every inch of added height gives added head pressure.

    OCD, .030 is a small orifice for a one inch tube burner. I use .25 for a 1/2 inch burner and .043 for a 3/4 inch burner.

    I tend to agree with your family person to an extent. The flower in the upper left corner doesn't seem to add anything. Another leaf there would look good to me, or a bud.

    The over 1000 F. is to burn out the bound water in the plaster. If you don't burn it out in the kiln, your molten metal will burn it out when you pour it and produce copious amounts of steam.

    Yes. None opf it is more than 1/4 inch thick if it can be avoided. Thicker places do accidentally happen, maybe 3/8, but if at all possible I try to stay under 1/4 and preferably 3/16.
